linux: run all defconfigs through 'make savedefconfig'

This tidies the cubieboard and olinuxino defconfigs and converts the
cubie2, truck and mele defconfig to the savedefconfig format.

This has no functional changes, only cosmetic ones.

sdcard_image-sunxi.bbclass: adding ext3 dependency (resolves #46)

Without this explicit dependency,
a race condition would be present between the generation of the sd image
and the generation of the ext3 file,
which leads to corrupt SD images in some circumstances.

Based on meta-raspberrypi commit https://github.com/djwillis/meta-raspberrypi/commit/a760ea5fa293a958ebcf1e5af0e6aa4518de4639

sdcard_image-sunxi.bbclass: make sunxi-sdimg image dependent on rootfs type

The rootfs may be using a filesystem type other than ext3 so it should
not be hardcoded.
